Fair-Rite Products Corp. [ Fair-Rite ] - Fair-Rite Products Corp., a ISO/TS 16949 registered company, is a leading, full line ferrite component manufacturer. Fair-Rite is known for utilizing innovative processes and materials. Fair-Rite offers a wide variety of components and engineering design support for EMI suppression and power applications. Their components for EMI suppression include split round and flat cable snap-on suppression cores, surface mount beads, and PC board suppressor cores. Ferrite is a class of ceramic material with useful electromagnetic properties and an interesting history. Ferrite is rigid and brittle. Like other ceramics, ferrite can chip and break if handled roughly. Luckily it is not as fragile as porcelain and often such chips and cracks will be merely cosmetic. Ferrite varies from silver gray to black in color. The electromagnetic properties of ferrite materials can be affected by operating conditions such as temperature, pressure, field strength, frequency and time. There are basically two varieties of ferrite: soft and hard. This is not a tactile quality but rather a magnetic characteristic. 'Soft ferrite' does not retain significant magnetization whereas 'hard ferrite' magnetization is considered permanent. Fair-Rite ferrite materials are of the 'soft' variety. Ferrite has a cubic crystalline structure with the chemical formula MO.Fe2O3 where Fe2O3 is iron oxide and MO refers to a combination of two or more divalent metal (i.e: zinc, nickel, manganese and copper) oxides. The addition of such metal oxides in various amounts allows the creation of many different materials whose properties can be tailored for a variety of uses. Ferrite components are pressed from a powdered precursor and then sintered (fired) in a kiln. The mechanical and electromagnetic properties of the ferrite are heavily affected by the sintering process which is time-temperature-atmosphere dependent. Ferrite shrinks when sintered.
